Spanish Imperfect Conjugation For Beginners

The first time I heard a friend in Mexico City tell a story about his old apartment, almost every sentence started with era, iba, or hacía. Nothing huge had happened yet. He was just painting the scene: the rent was cheap, the neighbors were loud, the coffee was bad, and the bus was always late. That is the imperfect in action.

In Spanish, the imperfect is the tense you use for background, habits, repeated actions, and past situations without a clear finish line. It often matches English ideas like “used to,” “was doing,” and “would” for repeated past actions. Once that clicks, the endings feel much less scary.

How To Form The Spanish Imperfect

Good news: the imperfect is one of the friendliest past tenses in Spanish. Regular verbs use just two sets of endings:

Mexican Spanish note: in everyday speech, you will usually focus on tú, usted, and ustedes. Textbooks often include vosotros forms like hablabais and comíais, but you do not need them to sound natural in Mexico.

One small gift from the grammar gods: most stem-changing verbs stop being dramatic in the imperfect. dormir → dormía, pedir → pedía, querer → quería. No weird stem change, just normal endings.

The Only 3 Irregular Verbs In The Imperfect

Yes, only three. Compared with other Spanish tenses, this is practically a spa day.

Ser: De joven, yo era muy impaciente. = When I was younger, I was very impatient.

Ir: Íbamos al tianguis los sábados por la mañana. = We used to go to the street market on Saturday mornings.

Ver: Veía esa serie mientras cenaba. = I used to watch that show while I was eating dinner.

Accent reminder: do not drop the accents in éramos, íbamos, veíamos, comíamos, or vivíamos. Those little marks are doing real work.

When To Use The Imperfect

Past Habits And Routines

Use the imperfect for things people did regularly in the past.

Spanish: Siempre tomaba café antes de entrar a la oficina.
English: I always used to drink coffee before going into the office.

Spanish: Mis padres cenaban tarde entre semana.
English: My parents used to eat dinner late during the week.

Ongoing Actions In The Past

Use it for something that was in progress. Very often, another verb in the preterite interrupts it.

Spanish: Leía un correo cuando sonó el teléfono.
English: I was reading an email when the phone rang.

Spanish: Caminábamos al metro cuando empezó a llover.
English: We were walking to the subway when it started to rain.

Descriptions And Scene-Setting

Use the imperfect to describe what things were like: weather, rooms, people, mood, traffic, chaos, the usual.

Spanish: El departamento era pequeño, pero tenía mucha luz.
English: The apartment was small, but it had a lot of light.

Spanish: Hacía calor y las calles estaban vacías.
English: It was hot, and the streets were empty.

Age, Time, And Other Background Facts

Spanish usually uses the imperfect for age and time in the past.

Spanish: Tenía veinticinco años cuando conseguí mi primer trabajo serio.
English: I was twenty-five when I got my first serious job.

Spanish: Eran las seis y todavía no llegaba nadie.
English: It was six o’clock and nobody had arrived yet.

Feelings, Thoughts, And Mental States

Use it for ongoing emotions, opinions, desires, and states of mind in the past.

Spanish: Estaba cansado, pero quería terminar el proyecto.
English: I was tired, but I wanted to finish the project.

Spanish: No sabía la respuesta, pero entendía la pregunta.
English: I didn’t know the answer, but I understood the question.

The imperfect paints the background. The preterite throws the chair through the window.

Useful Phrases That Often Show Up With The Imperfect

Imperfect Vs Preterite: The Fast Way To See The Difference

These two past tenses work together all the time. The imperfect gives background, repetition, or an action in progress. The preterite gives a completed event.

Another helpful note: Spanish often uses the simple imperfect where English uses “was doing.” So leía can already mean “I was reading.” You do not always need estaba leyendo. Spanish likes efficiency more than your old workbook did.

Common Mistakes And Easy Fixes

• Mistake: Using the preterite for a habit.
  Fix: Use the imperfect for repeated past actions. Todos los domingos visitábamos a mi abuela. = Every Sunday, we used to visit my grandma.
• Mistake: Forgetting accent marks.
  Fix: Watch forms like hablábamos, comíamos, íbamos, and éramos.
• Mistake: Expecting stem changes in the imperfect.
  Fix: Most verbs behave normally: dormía, not duermía; pedía, not pidía.
• Mistake: Treating fui and iba as interchangeable.
  Fix: iba = was going / used to go; fui = went.
• Mistake: Memorizing vosotros before forms you will actually use in Mexico.
  Fix: Prioritize yo, tú, usted, nosotros, ustedes.

Quick Reference Summary

• The imperfect is used for background, habits, repeated actions, descriptions, time, age, and ongoing past situations.
• Regular endings are -aba, -abas, -aba, -ábamos, -aban for -ar verbs and -ía, -ías, -ía, -íamos, -ían for -er and -ir verbs.
• The only irregular verbs are ser, ir, and ver.
• Many English “used to” and “was/were doing” ideas map to the imperfect in Spanish.
• In Mexico, focus on usted and ustedes; vosotros is not essential for speaking naturally.
• If the action feels completed and specific, check whether the preterite is the better choice.

Spanish imperfect conjugation gets much easier once you stop treating it like a random list of endings and start treating it like a storytelling tool. Use it to describe the scene, the routine, the mood, and the action in progress, and your Spanish will sound more natural fast.
